1.向数据库中插入数据
#!/bin/bash # send data to the the table in the MYSQL database MYSQL=`which mysql` if [ $# -ne 2 ] then echo "Usage:mtest2 emplid lastname firstname salary" else #脚本变量一定要用双引号，字符串变量使用单引号 statement=" insert into em_admin values(NULL, '$1', $2)" $MYSQL emwjs -u test <<EOF $statement EOF if [ $? -eq 0 ] then echo Data successfully added else echo Problem adding data fi fi
2.格式化输出数据
#!/bin/bash
#redirecting SQL output to a variable
MYSQL=`which mysql`
dbs=`$MYSQL emwjs -u test -Bse ‘show tables;’`
for db in $dbs
do
echo $db
done
#使用xml输出数据
$MYSQL emwjs -u test -X -e ‘select * from em_admin’
#使用table标签输出数据
$MYSQL emwjs -u test -H -e ‘select * from em_admin’
3.连接数据库并发送命令
#!/bin/bash #连接数据库 mysql=`which mysql ` #发送单个命令 $mysql emwjs -u test -e "show databases;" #发送多个命令 $mysql emwjs -u test <<EOF show tables; select * from em_admin; EOF
